Shrouded in mystery and misunderstanding, Aleister Crowley is one of the 20th Century's most revered occult figures. With the "Weiser Concise Guide to Aleister Crowley", readers are given a careful, comprehensive overview of Crowley's life and his life's work, including the basic principles of his magical practices. From the book: Crowley openly defied social conventions, challenging people to examine what they really believed, and why they believed it. He confronted blind faith with rational skepticism. Yet he likewise challenged the skeptic with scientific illuminism, a systematic approach to spirituality that he described as 'The method of science, the aim of religion'. Set aside your preconceptions and dismiss the rumours. Crowley was certainly a complex, controversial and colourful man, but the truth is far more interesting than the legend.
